Lobster preservation system

ABSTRACT

Fresh-caught lobsters are mounted in quick-connect containers for connection into or removal from a system, and transfer to at least one other similar system. The system provides temperatureconditioned aerated salt water which is continuously sprayed upon the lobster in the container from the time it is caught until it is finally sold. The lobsters are disposed in the container on foraminous trays having large, unobstructed, open mesh screen surfaces through which spray water and lobster waste continuously drain. Each tray is sprayed, and the spray water passes immediately through the open mesh surfaces of the trays so as not to accumulate thereon.

ffiie) TTORNEY LOBSTER PRESERVATION SYSTEM This invention relates to a storage and transportation system for live lobsters, to maintain them in a condition of good health, and the lobster meat in high quality as available from live, fresh-caught, healthy lobsters for substantially extended time periods.

More particularly, the method and apparatus are directed to a system of preserving live lobsters supported upon trays or cages in portable, quick-attachable containers for transfer from boat to truck to storage, each comprising a complete system into which the container is integrated. The live lobsters in each container are continuously sprayed with oxygen-containing salt water in a manner to wet and continuously wash the surfaces of the live lobsters with life-sustaining oxygenated salt water, maintained at a temperature controlled to correspond to a selected temperature, and preferably substantially corresponding to their natural habitat. The salt water contains oxygen supplied under pressure with an oxygen-containing gas sufficient to impart a life-sustaining quantity of at least 4 parts per million of dissolved oxygen to the salt water being sprayed.

Many attempts have been made in the art to preserve live lobsters, generally by immersing and even maintaining a moist fog upon a whole lobster, whereby it is wet with water and salt water, but the life of a lobster thus preserved was extremely short, a few days at most.

It has also been proposed to store the lobster packaged in ice, wet sawdust or seaweed; or, even better, in containers through which moist air is circulated with refigeration. In contrast, the present method will preserve the lobster many weeks in healthy condition.

In one aspect of this invention, the lobsters are mounted in a readily-storable and transferrable container comprising foraminous trays upon which the lobsters are disposed, the trays being supported separately in a tier within the container. The container is constructed with means for being quickly connected and disconnected into a system which provides within'the container a continuous, fine spray of aerated salt water at a temperature and composition controlled to approximate the lobsters native conditions. In this manner the live lobsters are allowed maximum exposure to the aerated salt water spray, applied substantially continuously upon their bodies for the total storage and transportation periods. The containers may be quick connected and disconnected to ducting comprising the system, which provides the continuous filtered temperature controlled and aerated salt water applied to the lobsters as a continuous spray There are drains cooperative with the containers for continuous withdrawal of the spray and lobster wastes from the container.

Such system includes containers of lobsters quick connected for lobster storage aboard ship as they are caught, quick disconnected and reconnected into a similar portable system aboard trucks, railroad cars and air craft for transport, and thence into the same system disposed in a warehouse or in salescounters. The containers in storage and transport are always connected into the same kind of system for continuous spray of the live lobsters over the total life period from the time the lobsters are caught and immediately placed in the containers, transported to storage or sales places, up to the time they are withdrawn from the container and sold as healthy, live lobsters. Since the life of the lobster according to the present system may exceed several weeks and up to about two or three months, the system becomes feasible to maintain the lobsters alive even for relatively long storage and transport periods within such time spans.

In another novel aspect of the present invention, containers are provided which include ducting disposed vertically through one or several trays upon which the lobsters are disposed, and the ducting includes nozzles pointed radially downward upon the lobsters for continuous wetting by direct spraying of the lobsters surfaces with a fine spray of aerated salt water continuously as a life-maintaining fluid for the lobsters.

In a third novel aspect of this invention, the system hereof comprises a source of salt water natural or artificialdesirably approximating a sea water corresponding ,to that of the lobsters native habitat in composition, and usually having a salt content in the range of about 20 to 40 parts per thousand, coupled with meansfor flowing or spraying fresh filtered sea water or salt water from storage under pressure for spraying. The system includes means for supplying air, including oxygen or an oxygen-evolving composition such as ozone under pressure to the water, whereby the water will be aerated with the oxygen-containing gas under pressure to impart to the salt water at least 4 parts per million of dissolved oxygen, the oxygen content ranging upward to a preferred 10 parts per million of dissolved oxygen. Such system includes means for refrigerating to control the temperature of the water to a preferred natural habitat temperature ranging from about 30 F up to about 77 F. I

The system further includes means for filtering the sea water, when natural, to remove natural sea water containing impurities; and, sometimes after aeration and pumping, the water is filtered again before use to exclude any possible contaminants that may be imparted in operation of the system from mechanical ele ments, such as pumps and compressors. The aerated water under a spraying pressure of at least 10 psig and usually in the range of 50 to 200 psig is continuously sprayed at the selected temperature upon the lobster disposed in the container.

Lobsters generally are of inshore type whose na tive habitat includes normal temperature variations from about freezing up to about 77 F, this type thriving best in the range of 41 F to 77 F. However, for temperature control for optimum handling of the inshore lobster, it is preferred to select the temperature at which the lobster was caught, varying it within the stated range only slowly over considerable periods of time, avoiding any sharp temperature changes.

The alternate offshore type of lobster is larger, inhabits deeper waters, and its natural water temperature ranges from about 30 F to 45 F, a preferred temperature range, and this type will not tolerate temperatures exceeding 50 F for substantial periods of time. Again, it is preferred to maintain lobsters within the stated preferred range in any case, and substantially at the temperature of the water in which the lobster wascaught.

The inshore lobster can tolerate substantial salt concentration variations within the above-stated range up to about 40 parts per thousand (4 percent); and, in any case, can tolerate above a minimum of 20 parts per thousand (2 percent). The offshore lobster, however, is preferably maintained close to its optimum salt concentration of about 2% percent and will not tolerate concentrations substantially below or above this range. For instance, the lobster will not tolerate concentrations higher than 3 percent or lower than 2 percent for substantial periods of time. A preferred salt range for these offshore lobsters is about 2.2 to 2.8 percent salt concentration for long time storage periods.

It is preferred, in any case, to use natural brine which has been filtered to remove both natural as well as artificially-introduced impurities. However, there are various known formulas for producing artificial brines comprising water made up to a salt content approximating that of natural brine. For this purpose a 22 parts by weight salt batch to form a synthetic salt water comprises l4.52 parts of sodium chloride; 3.52 parts of magnesium sulfate; 2.86 parts of magnesium chloride; 0.7 parts of calcium chloride; and 0.33 parts of potassium chloride as the major salt components dissolved in 1,000 parts of water, sufficient to form a 2.2 percent solution in a typically-useful synthetic brine for both types of lobsters. Natural sea water, however, contains trace quantities of many other salts. This synthetic salt as formulated can be dissolved in larger or smaller quantities of water to form a brine solution whose salt content will be in the range as stated above.

The water is aerated under substantial pressure to introduce a substantial saturation content of oxygen in the water in the selected temperature range at a pressure from to 200 psig. The dissolution of the oxygen in the water under such pressure may be effected by mechanically compressing the air or oxygen and aerating the water as by bubbling the air or other oxygen source through the water under that pressure to dissolve the oxygen in the water in the desired quantity, as stated.

In an alternate method, air or oxygen stored compressed in cylinders may be a suitable source with which the water may be aerated under pressure. Water may be independently pumped and aerated, or the aeration per se may form the source of power to flow the air into the water and pass the aerated solution through nozzles as an aerated sprayupon the live lobsters. The operation in the manner described will produce a saturation condition ofdissolved oxygen at absolute quantity, being variable with both the pressure applied as well as the temperature of the water.

The invention is further described with respect to the drawings wherein:

FIG. 2 is a schematic view showing several containers interconnected into a system: 7

FIG. 3 illustrates schematically mounting of a group of containers in a shipboard system;

FIG. 4 is an end view of the ship of FIG. 3;

FIG. 5 illustrates a system of mounting containers in a truck;

FIG. 6 illustrates a single container depicting the arrangement of trays in said system; and

Referring first to FIG. 6, a portable container 10, shown here to be rectangular, but which may be cylindrical or other desirable shape, is fitted with a quickdisconnect coupling member 12. The coupling member 12, as shown in detail in FIG. 7, may be merely a bayonet joint but other known types of quick-disconnect joint members may be substituted. Such joint is formed between a female coupling member 14, having a helical groove 16 cut into the cylindrical wall 18 thereof, which will receive a projecting pin 20 mounted normal to or upright from the cylindrical inner wall 22 of a male coupling member 24. The male member may have a flange 26 and a resilient gasket 28, so that by twisting of the female coupling member the joint is coupled and uncoupled. While either the male or female coupling member may be rotatable loosely, in some known constructions, it is preferred to attach the male coupling member 24 to resilient ducting such as a rubber hose 30, which will accommodate any twisting motion for purposes of coupling and uncoupling. The coupling member for this purpose may be fastened as by a rough-threaded plug member 32, to the rubber hosetype duct 30, secured thereto by large, steep-pitched threads 34, frictionally engaging the upper hose end 30 in a conventional manner.

The container 10 has centrally mounted a duct 36 which extends vertically through the center of the container to a point near the top thereof, where it bends to join a horizontal duct 38. The duct 38 passes through a slot cut through the side 39 of the cover 35, and the duct terminates in the female coupling member 14 of the quick-disconnectjoint 12.

The container 10 comprises a top closure member which frictionally fits upon four rectangular side walls 40, the walls being suitably heat insulated by a lining 41, which may comprise an extra layer of metal as an inner liner, and having supporting insulating sheet 43 between inner and outer layers. The vertical body of the duct 36 is fitted with several nozzle-like projections 42, each disposed a few inches above an unobstructed, open mesh screen-like tray member 44, said nozzles projecting a fine spray of liquid angularly downward and radially in all directions to continuously wet lobsters disposed upon each tray member 44. The several tray members 44 are mounted in a vertical tier, each supported upon the inner walls of the container, upon angle iron or bracketing members 46 to be supported vertically thereon only by their gravitational weight. The centers of each tray comprise foraminous screening 48 except in the area of the duct 36 which is annularly open to allow the duct 36 to pass downward from the top of the container through the center of the several layers of screen, as shown. As clearly illustrated in FIG. 6, the foraminous open mesh screening 48 permits the spray water to pass immediately through each tray member 44, so as'not to accumulate on thereon. A door 50 is fastened to one side 40 and is supported by hinges 52 for swinging movement to open horizontally, allowing the trays with lobsters thereon to be filled into and removed from the container 10 to rest upon brackets 46.

After positioning of the several trays therein, the duct 36 attached is inserted vertically downward followed by lowering the cover member 35 to position and secure the duct 36 as shown centrally of the several screens in spray position, with the nozzles in spray position upon the screens. The movement of the duct 36 for insertion and removal together with the cover is effected with the coupling member 12 uncoupled. After assembling of the container, the lobsters can be individually added to or removed from the trays from time to time by opening the door 50. Upon removal of duct 36, the entire tray may be inserted or removed from the container.

The container is then quick coupled into a systemcomprising numerous containers 10. Such system, as shown diagrammatically in FIG. 2, comprises several containers 10, each quick coupled through coupling members 12 to a system comprising a main duct 54 branching into branch ducts 56, each branching duct 56 communicating with a duct 58 servicing two containers 10. The duct 58 is fitted with valves 60, each of which can be closed when the container is being removed by uncoupling the quick-coupling member 12.

Drain outlets 62 cooperate with a drain outlet 61 in the bottom of each container through which water and waste from the lobster is continuously washed and dripped into outlet ducts 62 which join a main drain pipe 64, leading out of the system for waste and water disposal.

The system also comprises a source of sea water [not shown] which is passed into a duct 66 controlled by a valve 68, passing thence to a first filter 70 and to an intermediate reservoir 72. A source of compressed air or oxygen 74 feeds oxygen under selected pressure through a duct 76, controlled under pressure by a gauge 78. The gas joins and aerates the liquid passing through a duct 71, passing thence to the intermediate storage tank 72. Brine from storage tank 72 is circu lated to a refrigerating device [not shown] through line 73 for close temperature control. The brine is withdrawn under pressure of the gas in storage tank 72 by way of duct 80, passing into main feed lines 54 for spray distribution into each of the containers, valves 60 being open. A second intermediate filter 82 is sometimes usefully placed in duct 80, particularly where circulating pumps or air compressors are used to effect the spraying, the second filter 82 being used to remove any possible contamination from such alternately used mechanical elements.

The system shown in FIG. 2 is mounted as duplicated systems on the boat where lobsters are being caught, the fresh-caught lobsters being inserted into the con tainers 10, and quick connected into the system as shown in FIG. 2. Such system is mounted in a boat, as shown in FIGS. 3 and 4, each lobster being empla'ced upon a tray and sprayed through the nozzles 42 continuously from the time they are caught, with a lifesustaining supply of a light coditioned spray of aerated salt water. As the catch increases from day to day, the lobsters remain alive by being continuously sprayed with sea water under pressure and at controlled temperature. Then the catch is brought into port after several days or even weeks, the containers being then transferred by quick disconnecting and reconnecting into a similar system mounted for transportation in a truck overland as shown in FIG. 5. As on the ship, the containers mounted in the truck are quick connected to the system for continuous spray of aerated salt water in controlled temperature and pressure as they are being transported.

Similarly, the transported catch is then transferred to the same system disposed in a warehouse, where they may be further stored, or reconnected directly to a similar system in a market where they are being sold, each container being connected to the system and continuously being sprayed with a life-sustaining aerated spray of salt water and the lobsters are maintained at controlled temperature until they are actually sold. Such process which may cover a period of several weeks of maintenance of the live lobsters from the time they are caught until the time they are distributed by actual sale to the user, provides continuous spraying except for the few minutes that; the containers are disconnected from one system and reconnected into another. Hence, the lobsters are maintained continuously alive by substantially continuously spraying with the temperature controlled and aerated salt water.

FIG. ll shows the system diagrammatically, indicating in process terms how it is operated. For instance, the sea water passes through a line 66 to a first filter 70; and air from a compressor-69, or as shown in FIG. 2, from a. compressed oxygen or air tank 74, passes through line 76 to join filtered sea water passing through duct 71 and thence to a storage tank 72. The storage tank 72 is connected with a. refrigeration means 73 which withdraws a portion of the aerated water and cools it to a preselected desired temperature, whereby the brine in storage tank 72 is aerated under selected pressure and controlled to a desired temperature. It is withdrawn .by way ofline 80 and sent through a second filter 82, passing thence into said distribution lines 54 and 56, and finally passing by way of quick-disconnect joint. 12 for spray into the thermally-insulated waterproof containers. Residual water and wastes are withdrawn and disposed of extraneously through line 64.

The operation of the system is further described in the following examples:

EXAMPLE I Inshore small rock lobster harvested from a depth of about one to five fathoms at a temperature ranging from about 60 F to 75 F are placed upon trays immediately as caught in a container with sufficient spacing between lobsters to allow free wetting with the continuously-applied spray of salt water. The salt water is the natural brine of the area in which the lobster was caught, or a synthetic brine of the type described above, containing about 30 parts per thousand of said synthetic salt mixture. When first caught, the temperature of the spray water is adjusted to approximately the temperature of the water in which the lobster originally existed; but, thereafter, the temperature is gradually lowered by cooling to about 45 F, and is maintained within 21 2 F temperature range of the said 45 F for the preserved life of the lobster. The original spray brine which was natural salt water of the lobsters habitat, is first filtered; the water is then aerated with air from a mechanical air compressor, injecting air into the water at the pressure of about 50 pounds per square inch; and the aerated water is passed into a storage tank from which the water is then taken for subsequent spraying.

The temperature of the water in the storage tank is ad- I justed by circulating the water through refrigerator coils to maintain the preselected temperature. The water contains about between 8 and l parts per million of dissolved oxygen, maintained under pressure of 50 pounds per square inch as supplied by the compressor. The water is withdrawn from the storage tank and given a second filtration and then passes through nozzles to be evolved as a very light spray at a rate to continuously wet the lobster with the fresh aerated salt water, a spray which is maintained substantially continuously for the life of the lobster in the container. The wash water dripping from the lobster, plus any body wastes, are washed to the bottom of the container and withdrawn through a drain as shown in the system pictured in the drawings and described above, the lobster being continuously sprayed only with the fresh salt water, as thus described. When the catch of the ship or trawler in the containers in which the lobster has been initially stored is complete, and the trawler comes into the harbor, each container having the structure described above is quick disconnected from the salt water spray system and quickly reconnected to the same or similar salt water supply system mounted in a truck, as shown in FIG. 5, for transportation to a point of storage or market. The truck has mounted thereon a similar system to apply a similar spray of salt water, maintained under similar aerating conditions and tem-' perature. Upon arrival at their destination, the con-' tainers are again quick disconnected and again recon-.

nected to a similar system for stationary storage or sale.

EXAMPLE ll Offshore large lobster harvested from a depth of 40 to 200 fathoms and caught at a water temperature of about 35 to 40 F, are stored as caught on trays disposed in containers as described above, and sprayed with oxygenated salt water, either the natural brine approximating the water from which they were taken or a synthetic brine containing about 25 parts per thousand of synthetic salt having the composition stated above, the salt water containing about 10 parts per million of dissolved oxygen formed by aerating the salt water with air at a pressure of about 90 pounds per square inch, the water being maintained in the range of 35 to 40 F, close to the exact temperature of the water in which the lobsters were caught. The lobsters are continuously sprayed with a wetting supply of the salt water as they are mounted in said quick-disconnect container aboard the ship, and the containers are then transferred in port to atruck having a similar system in which the same temperature is maintained while the continuous spraying of the lobster in the containers is maintained. Finally, the disconnect containers are integrated into a storage system in a warehouse or at the market, where they are to be sold, and are still continuously sprayed with the same aerated salt water solution until they are sold. The lobsters, even after a couple of weeks, are found to be healthy and the lobster meat is indistinguishable from immediately fresh-caught lobster.

According to the system as herein above described, the lobsters disposed in containers quickly connected into a system, are continuously sprayed over their lifetime from the time they are caught until they are sold, with a life-sustaining supply of natural salt water or one in which the salt is carefully controlled to the range stated above; and at a temperature for inshore lobster in the range of to 77 F with only slow changes of temperature from its natural habitat to that of the refrigerated condition; and, in the case of offshore lobster, the temperature is again preferably that of its natural habitat but is, in no case, greater than about 45 F, as also extensively disclosed above.

As stated, except for the few minutes of connecting and disconnecting the containers in which the lobsters are originally stored, the lobster is continuously maintained under a spray of the aerated salt water containing a life-sustaining quantity of dissolved oxygen of at.

least 4 parts per million; and the salt water is maintained at the selected temperature.

Certain modifications will occur to those skilled in the art. As indicated, the system may apply to other vehicles such as air craft, and other types of sea vessels or land vehicles.

Moreover, while the invention is primarily directed to the maintenance of lobster, both inshore and offshoretypes, for extraordinarily long periods of time, the system will also be applicable to other species of shell fish to maintain them alive for indefinitely extended periods. For instance, such shell fish as crab,

' particularly red crab, shrimp, prawn and krill may be preserved by the present system.
